Actually, this could be a very cool technique for negotiating an encrypted exchange between two peers on an untrusted network. One feasible sequence could look like this.
The peers share a protocol to translate a sequence of port knocks into a usable data stream. There would have to be some provision to filter out 'noise' or non communication based port knocks (not extraordinarily difficult, since you can just retry if required).
One peer uses a sequence of port knocks to inform the other of its IP address, public encryption key, and desired port to be used for this communication session.
The other peer uses a sequence of port knocks and the IP address to pass back its public key and desired port to be used.
The first peer encrypts an arbitrary stream of data packets with its private key and the second peers public key, and sends those packets to the port suggested by the second peer.
The second peer does the same.
More interesting, is that you could use this to bypass the "tracker"/"hub" issue with most peer to peer networks. As soon as you want to join a peered network, the client could just start port knocking random IPs until you get a response from someone who is already a member. The time required to find a member would, of course, scale inversely with the number of members. From that member you get a list of valid P2P network IPs that he knows about and in return you pass any other valid P2P IPs you discover.
One key component that I did not see addressed in the article is how you control this device. Is there a remote that lets you interact with a TV friendly menu system?
Of course there's a remote. You can also control it via the serial port or by telneting into the HD1000. And, if you'd like to control it in ways we don't currently provide, grab the SDK (once it's available) and code away.
So I guess I have three main questions.
First, does the HD1000 support IR based remotes out of the box, or would I have to install appropriate hardware and drivers myself?
Second, if the HD1000 does support IR hardware, is the software interface designed to be used while looking at a standard television from a respectable distance?
The reason I ask this is that I have yet to see an embedded media player that allows me to use a IR remote device to navigate directory structures on remote fileservers, play, pause and stop various media players, etc from standard viewing distances with any degree of sophistication.
Third, if this capability is not available, would you be interested in paying 'someone' to design and build either the hardware required, the software interface, or both.;-)
One key component that I did not see addressed in the article is how you control this device. Is there a remote that lets you interact with a TV friendly menu system?
This question arises because one of the main headaches associated with my current streaming media system (home built) is that using the wireless mouse and keyboard to navigate is difficult from a reasonable TV/audio viewing and listening distance...
If they have addressed this issue at all, I will have to buy one. I would love to get away from requiring a full PC in my entertainment rack since all it does is stream data from my fileservers anyway.
And yes, I have tried other embedded devices, but most have proprietary OS, and linux ones do not generally support my specific set of audio and video requirements.
Not only is it a Ben Franklin quote, I have been using it as my sig. This society is an increasingly selfish and shortsighted one, and the tradgedy of the commons is... well... all too common.
Oddly, it appears to me that the best response to problems like this is to use technology to redefine the problem. Make signals on the units used by emergency vehicles to affect traffic lights digitally signed and encrypted in a dynamic fashion - then not only would it be difficult to replicate for third parties, but you could use the same means to keep data about emergency vehicle path and response times.
Strangely, many other versions of the prisoner dilemma respond well solutions that use technology to redefine the terms of the problem.

Since the neutrons emitted during fusion can generally be absorbed by water (generating relatively harmless deuterium, tritium, helium 4, etc), has anyone considered submarine fusion power plants? An automated fusion plant could be tethered to a surface ship or platform and maintained at arbitrary depth. This volume of water would absorb any neutrons emitted by the fusion process and essentially generate no difficult to store long half life radioactive waste products.
In a worst case scenario, release the tether, and the plant drops into the sea floor, where it would eventually make its way to one of the intercrustal zones and be forced into the mantle.
You could use the pressure at depth to help contain the reaction.
Folks could hardly complain about envionmental impact, since we have lots of fairly dirty fission powered submarines running around already.
Anyway, seems like an interesting way to handle potential fusion waste products and make fusion easier to sustain by using 'free' pressure differential available at depth...
I also have a 8k+ SF/fantasy/horror book collection, and one of the best authors i have yet to see mentioned here is Ian McDonald.

All very very good science fiction. He is up there with Sterling/Gibson/Vinge/Banks/ etc etc Check here for more details http://www.sfsite.com/lists/ianmc.htm
Another favorite that does not seem to make most lists is Daniel Keys Moran. The 'Long Run' world is quite spectacular.
There are hundreds of other overlooked authors, but those are two of the best SF ones you might have missed.

Now that we finally know the right question to match the ultimate answer, I suppose the universe can end.

Somehow it does not surprise me that Douglas Adams and the Monty Python crew are the secret masters of the universe.

It is not at all clear that the credibility of our current president *is* any better than that of a representative random quote from Hee-Haw.
With Bush, Arnold, Jesse Ventura, and the other cast members, I fear our democratic process has entered the realm of post modern magic realism.
